The signs and symptoms of Peritoneal mesethelioma (mesethelioma cancer that affects the lining of the abdominal cavity) are as follows:

Abdominal pain (ranging from acute to severe)

Stomach pain

Accumulation of fluid in the peritoneal cavity ( ascites)

Swelling of the abdomen (due to the accumulation of fluid)

An abdominal mass

Breathing problems

Bowel obstruction

Nausea

Vomiting

Fever

Anemia (a low count of red cells in the blood)

Weakness

Loss of appetite

Weight loss (due to no apparent reason)

Blood clots in the veins

Blood clots in the arteries of the lungs

Abnormal blood clotting

Severe bleeding in body organs

Yellowing of the eyes and skin (Jaudice)

A low level of sugar in the blood

Pleural effusion

Abdominal pain and swelling (due to the accumulation of fluid in the abdomen) are usually the most common symptoms of this type of mesothelioma. Weight loss is another common symptom of peritoneal mesothelioma and is usually more dramatic than other forms of mesothelioma. Peritoneal mesothelioma affects also the intestines, liver and other structures in the abdominal cavity. The ability of the body to make blood clots is impaired since the liver plays an important role in producing the substances to control bleeding. As the tumour spreads beyond the mesothelium to other parts of the body other symptoms may include trouble in swallowing or swelling of the neck or face.
